Staying logged in., Forum works, site doesn't... Options

[poeticvanity]

Well, I looked around and didn't see this addressed by anyone else.

I can be logged into the forums here just fine, but if I try to be logged in for the rest of the site, it doesn't work. I tried going in to sign up for the tracker, and when I click it, it brings me to the login screen. So I log in, and it goes back to the page I was at, and the process just repeats. But as you can see, obviously, I'm logged in now and have no problems on the forums.

I'm not sure why this is happening, because I've tried on 3 or 4 other computers, with different settings and different internet, and just nothing works. Am I missing something?
